--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Martin Jambor <jamb...@gcc.gnu.org>: https://gcc.gnu.org/g:988fbc636639621dadc5cecbe77aa3f9aefedefb commit r12-8368-g988fbc636639621dadc5cecbe77aa3f9aefedefb Author: Martin Jambor <mjam...@suse.cz> Date: Wed May 11 23:25:40 2022 +0200 ipa: Release body of clone_of when removing its last clone (PR 100413) In the PR, the verifier complains that we did not manage to remove the body of a node and it is right. The node is kept for materialization of two clones but after one is materialized, the other one is removed as unneeded (as a part of delete_unreachable_blocks_update_callgraph). The problem is that the node removal does not check for this situation and can leave the clone_of node there with a body attached to it even though there is no use for it any more. This patch does checks for it and handles the situation in a simlar way that cgraph_node::materialize_clone does it, except that it also has to be careful that the removed node itself does not have any clones, which would still need the clone_of's body. Failing to do that results in a bootstrap failure. gcc/ChangeLog: 2022-04-27 Martin Jambor <mjam...@suse.cz> PR ipa/100413 * cgraph.cc (cgraph_node::remove): Release body of the node this is clone_of if appropriate. gcc/testsuite/ChangeLog: 2022-04-27 Martin Jambor <mjam...@suse.cz> PR ipa/100413 * g++.dg/ipa/pr100413.C: New test.
